Abstract: PURPOSE: To obtain the optical head device capable of generating a light spot smaller than a diffraction limit value determined by the wavelength of a light source and the numerical aperture of an objective lens and also performing good recording and reproducing without generating noise but high density. CONSTITUTION: Intensity of light in the vicinity of the center in a cross section of luminous flux of laser light is decreased by an optical modulator 3 in intercepting light with a light intercepting plate in a linear shape inclined at a certain angle to y-axis. Consequently, a light spot on an information surface of an optical disk 6 is shrunk in both x- and y-directions to be smaller than a light spot formed without using the optical modulator 3. An inclined angle of the optical modulator 3 is set to an optimum value based on line density and a track pitch of the optical disk 6 to be used, and adjustment is made not to allow a sidelobe to irradiate pits in front and rear and adjacent tracks, which are being irradiated with a main beam.

Title: Printing plate
Inventor: SAIKI MASARU
IPC: B41N1/00
Filed: 1991-09-26
Abstract: PURPOSE:To improve the corrosion resistance and abrasion resistance of a printing plate and to easily confirm the abrasion state of the printing plate by the naked eye by coating a plate to which a printing pattern is applied with a ceramic compound whose hue is different from that of the plate to form a printing plate. CONSTITUTION:A printing plate 1 is formed by coating a plate to which a printing pattern 1A is applied with a ceramic compound whose hue is different from that of the plate. As an embodiment of the plate, an SKD steel plate, an SK steel plate or an SU steel plate is designated and, as an embodiment of the ceramic compound, there is nitride. Since the ceramic compound is applied in a single layer or a double layer, corrosion resistance is enhanced and preservation and control become easy and the coefficient of friction with a doctor blade lowers and the life of the printing plate and the doctor blade becomes long. Since the hue of the ceramic compound is different from that of the plate, the abrasion state of the coat layer can be easily confirmed on the basis of a hue change by the naked eye. The ceramic compound can be applied by ion plating.

IPC: C09D7/12
Filed: 1984-12-27
Abstract: PURPOSE:To enlarge saturated flux density of magnetic property which is required for a magnetic stripe by using specific metallic powder as magnetic substance. CONSTITUTION:Ferromagnetic metallic powder, which is obtained by vapor- phase contact reductive reaction of acicular ferro-hydroxide particulates adhered and denatured using reductive gas, is used. Residual magnetism (phir) can be improved markedly and also large regenerative output is obtained as electromagnetic converting characteristics. This fact means as follows, i.e. sufficient recording density can be obtained, even if the thickness of a magnetic layer is reduced less than a half of the magnetic layer, unlike conventional technique which the magnetic layer is required to be thick, and still more the technique comes to be large merit as to card processing too.

Title: Stabilization method of ferromagnetic metallic particulate
Inventor: TAGAWA KIMITERU
IPC: G11B5/712
Filed: 1984-12-27
Abstract: PURPOSE:To improve remarkable oxidation stability without affording variation to magnetic property by a method wherein after an oxide film is formed on to a surface of ferromagnetic metallic particulates whose main body is iron. CONSTITUTION:Heat-treatment is performed to particulates, whose surface is oxided within temperature's range at 100-500 deg.C and desirable at 200-400 deg.C under an inert-gas atmosphere such as a nitride gas. Since the heat-reeatment at less than 100 deg.C takes very ong time to get desirable effect, it is not practical. The heat-treatment at more than 500 deg.C has a merit that can be treated for short time however, since basic unit particle's crystal growth of ferromagnetic particulates is occured in company with crystal growth of an oxide film, it is unsuitable for the use of magnetic recording.

IPC: F24H3/04
Filed: 1990-10-13
Abstract: PURPOSE:To simplify a control by sequentially altering burning amount of kerosine by a small amount at each one unit without altering it at once if the burning amount of the kerosine is altered. CONSTITUTION:An ambient temperature is compared with a target temperature, and a necessary burning amount is decided. Then, the decided amount is compared with a present burning amount, and if they coincide, there is no increase/ decrease in the burning amount, and hence it is ended as it is. When the burning amount is increased, burning amount of kerosine is increased by one unit. If the amount increased by one unit is not yet insufficient as compared with a target burning amount, it is further increased. This is repeated. When both coincide, it is ended. If the amount is reduced, the burning amount of the kerosine is decreased by one unit. If the amount decreased by one unit is still excessive as compared with the target amount, it is further decreased. This is repeated. When both coincide, it is ended.
